To all whom it may concern:

Be itknow'n that I, EDWARD H. MGCLOUD, a citizen of the United States,residing at Columbus in the county of Franklin and State of bio, haveinvented a certain new and useful Improvement in Doors, of which thefollowing is a specification.

This invention relates to the type of door that includes two sections,one of which is slid up in front of the other, the two sections beingthen tilted together from the door opening to horizontal position; andthe object of the invention is to provide a simplified and improvedconstruction of this type whereby its operation. is made easier and moreeiiicient.

This invention is embodied in the example shown in the accompanyingdrawings, set forth in the following description and finally claimed;

In said drawings Figure 1 is a view in elevation looking at what isordinarily the inner side.

Fig. 2 is a vertical section on the line III-Ill, Fig. 1 looking to theleft.

Fig. 3 is a horizontal section on the line II, Fig. 1, on a largerscale.

Fig. 4: is a' similar section? on the line 11-11, Fig. 1.

In the views 5, 5 designates vertical channels which are to be suitablysecured to the vertical portions of the doorway casing. 6 designates thelower door section and? the lower section 6 are each provided withrollers 8 journaled in brackets 9; and connected with said brackets arechains or cords pass- 1 ing upward over suitable pulleys l0 and 11 to acounterbalancing weight 12. The upper corners of the lower section areeach also provided with a flan ed roller or wheel 13 for the purpose toe hereinafter referred to.

The upper section 7 in its vertical osition is sup orted by means ofsmall ro lers 14 journa ed on bearings projecting laterally from theupper corners of that section, said rollers resting on short trackportions 15 on brackets designated generally as 16.- The vertical edgesof the upper section are provided with angle bars 17 having one webofiset from the face of the section so as to form channels in which thevertical edges of the lower section travel when that section The lowercorners of the:

is raised. When the lower section is raised to the position where itcoincides horizontallyor is opposite the upper section the lattersection is engaged by hooks 18 fixed to the lower portion of the lowersection so that the two sections are coupled for further movementtogether in the same direction.

The brackets 16 are provided with curved grooves 19 that are engaged bythe central or projecting portions of the wheels 13; and the lower rimof said groove is extended horizontally as a track 20 upon which thewheels 13 ride to support the upper portions of the two sections aftersaid wheels leave the grooves.

The upper section 7 is provided at each of its upper corners with alatch pivoted at 21, said latch having an arm 22 to engage a shoulder 23on the bracket 16 when the upper section 7 is in vertical position and adependent arm 24: having a downwardly and outwardly inclined end 25.When the lower section is raised the bearings of the rollers 13 strikethe inclined ends 25 and raise the latching arm 22 thereby releasing theupper section permitting it to be defiected outward from the wall withthe lower section, the lower section being directly deflected by theengagement 0 the rollers 13 with the curved grooves 19. The upper wallof the grooves 19 thus causes initial outward deflection of the upperportions of the coupled sections but after some considerable deflectionthe rollers 13 ride on the tracks which support the sections at thoseportions, while the lower portions are supported by the chains or cordsas indicated by broken lines Fig. 2. By raising the lower portions ofthe sections sufficiently the sections can be brought to substantiallyhorizontal position. To permit the deflection of the sections at theupper portions of the channels the latter at'those portions are cut awayand made narrower as seen at 5*. 4

The character 26 designates an endless chain running over a sprocketwheel 27, the shaft of which has a spur gear 28 to engage a spur gear 29on the shaft of the pulley 11. B these or other familiar means the door,w en heavy, can be conveniently opened and closed. To close the door theoperation is merely reversed. When the coupled doors drops to latchingposition the \ lower section descends by gravity or wise as may hedesired to close the lower portion of theopening.

What l claim i ,l. A door including, in combination, an upper and alower'section, means for taising the lower'section into coincidence'withthe upper sectiomrne'ansengaginp; the sections with each other, a trackupon which the upper section is hung and is rnoVahle-face-wise from thedoor opening, deflecting means, and means on the lower section forengaging said deflecting means, and a second track to support the upperends oi the combined sections when deflected.
